I just purchased 5 Hipshot HB6 tuners, have not yet installed them, and all but one of them has pronounced variation in the resistance felt when turning the key, as if one of the gears was slightly elliptical. For example, turning the key 1/2 a turn feels normal, then suddenly for the next 1/4 turn the resistance lessens and the key turns much faster with the same amount of hand force applied. Is this normal, and/or should it disappear when installed with strings providing tension? I'd rather not install them if it is something that warrants a return.
Thanks
